I'm just wondering if, as a Professor, you get paid only by the school you teach at, or if you receive additional income for your research that you do. For instance, let's say you're doing some investigation into accreting binary systems and you get $50k in research grants from NASA; is that money to be used purely for research purposes? (i.e. time on a telescope, travel to and from symposiums to present results, etc) Or do research grants ever include ear-marked cash for the researcher's own pay? Just curious... parts of me think that the researcher's time is worth money, but at the same time, he/she is also being paid by the school for the express purpose of doing research and bringing renown to their school. How does it all work? Just curious what the future might hold... I'm still on the fence about going into the private sector, or continuing as a grad student, and income is an obvious point of consideration.
